LM340T-15/NOPB Description

Short technical summary and product information.

The Texas Instruments LM340T-15/NOPB is a monolithic 3-terminal positive voltage regulator designed for various applications requiring a stable 15V output. It can deliver up to 1.5A of output current with an input voltage range of 7.5V to 35V.

 

Key electrical specifications include a typical quiescent current of 6.5 mA and a dropout voltage of 2V at a 1A load. The regulator features internal current-limiting, thermal shutdown, and safe-area compensation, making it highly reliable. It offers a typical PSRR of 50 dB at 100 KHz and an accuracy of 2.5%.

 

This device is suitable for applications requiring a fixed positive output voltage. The TO-220-3 package is designed for through-hole mounting, and the operating temperature range is from 0°C to 125°C. The LM340 family is known for its robustness and ease of use, often requiring minimal external components for stable operation.
